Description

Noiseless Mouse {A noiseless mouse for computer}

The present invention relates to a computer mouse, and in particular, by significantly reducing the click noise generated when pressing or releasing the mouse button, it is easy to use not only in general environment but also in a space where quietness is required such as a library or a conference room. It relates to a silent mouse.

In recent years, the proliferation of notebooks has made it possible to use computers anywhere and anytime.

However, when using a computer, the mouse used together is almost always a unique 'click' sound when a button is pressed and released. In a place where quietness is required, such as a library or a conference room, the mouse click is often noisy.

Of course, when using the notebook in a place where quietness is required because of this problem, the touchpad mounted on the notebook is used, but the operation is inconvenient compared to the mouse, it was not possible to use quickly.

The click sound of the general mouse is generated from a tact switch inside the mouse connected to the button. The tact switch structure and operation principle thereof are as follows, when the mouse button is pressed as shown in FIG. 1. The second pressing portion 2 moves downward to press the center portion of the metal dome 3 of the circular dome shape located on the bottom.

At this time, the pressing force applied to the center of the metal dome is concentrated on the bottom edge of the metal dome, and thus the bottom edge serves as a supporting point for supporting the pressing force.

If pressure continues and the support capacity of the edge exceeds the limit, the central part of the boundary line bent in a circle along the edge of the metal dome is instantaneously bent downward, and the center point is connected to the bottom contact terminal (4). The contact is made in the form of a click signal.

The unique sound generated when pressing and releasing the mouse button is a kind of collision sound and metal dome that are generated when the center part contacts the terminal 4 and the pressing part while the metal dome 3 is folded down as described above. The trembling of the metal dome that occurs during the restoration process.

The noiseless switch that minimizes the operation noise has been devised by the user (utility model 20-0452772), but the operation noise of the button is not limited to the switch itself. The sound is generated by vibrating the circuit board, and the vibration is transmitted to the upper part of the mouse through the pusher that presses and fixes the circuit board to generate sound.

In addition, all of the above sounds are generated in the empty space inside the mouse housing, and the noise becomes louder.

The present invention is proposed to improve the problem that the noise generated by the vibration of the switch board as well as the circuit board and the mouse case as described above, all these noises are amplified in the empty space inside the mouse,

By improving the method of fixing the circuit board, the noise generated while the circuit board vibrates and the vibration transmitted to the upper part of the mouse case is reduced, and the noise inside the mouse is reduced to minimize the amplification of the noise. At the same time, the noise generated is to be absorbed so as to provide a silent mouse that does not feel uncomfortable to use even in a quiet environment.

The noise-free mouse of the present invention for achieving the above object,

The basic configuration is composed of a case, a mouse button provided in the case, a switch unit which is operated by a mouse button and connected to a circuit unit in the case.

The circuit board of the circuit unit is pressed in a state in which the circuit board is directly contacted by the press bar protruding from the case, and the circuit board is pressed by the press bar through the buffer member without being fixed.

In addition, an elastic and sound-absorbing blocking member is positioned above the circuit board so that the blocking member contacts the upper part of the case and the circuit board during assembly so that the inner space of the mouse is divided into a space with a switch and a space without a switch. The space is reduced, characterized in that the ringing space is reduced.

The present invention made of the above characteristic configuration,

When the mouse button is pressed or released, the vibration generated by the switch unit is absorbed by the buffer member that is in contact with the presser bar on the upper part of the mouse through the circuit board on which the switch unit is seated, thereby reducing the vibration of the circuit board and reducing the vibration sound. The vibration transmitted to the upper part of the mouse case is also reduced, so that the vibration sound of the upper part of the mouse is reduced.

In addition, an elastic and sound-absorbing blocking member located above the circuit board divides the inner space of the mouse into a space with and without a switch or reduces the empty space with a switch, thereby amplifying the noise generated from the switch. In addition to reducing the noise, the blocking member absorbs some of the noise of the switch unit, thereby greatly reducing the noise.

In addition, the blocking member is placed between the upper case and the circuit board to press both sides, thereby reducing the vibration of the upper case and the circuit board to reduce the generation of noise.

Hereinafter, with reference to the configuration illustrated in the drawings will be described an embodiment of the specific configuration and its operation of the present invention.

The noiseless mouse of the present invention is largely composed of a case 100, a circuit unit 200, and a switch unit 300 as shown in FIG. 2.

First, the case 100 is an element forming the external shape of the mouse, and has a structure in which the upper case 110 is covered on the lower case 120 in which the circuit unit 200 and the switch unit 300 are installed.

The upper case 110 is a part which is directly gripped by the user's hand, and a wheel hole 113 is formed at the center of the front surface of the upper surface of the wheel button 112, and the first and second buttons 114 and 115 are provided at both sides of the wheel hole 113. ) Is provided, and a plurality of presser bars 116 which serve to press the circuit board 220 provided on the lower case so as not to move are formed inside.

The overall shape of the upper case 110 has a curved surface as a whole so as to have a good grip feeling as well as a conventional mouse, as well as to avoid excessive strain on the finger joints during the repeated operation of each button 112, 114, 115. Ergonomically manufactured.

Of course, the shape of the upper case 110 is not limited to a particular shape and can be variously applied various modifications.

The lower case 120 corresponding to the bottom of the case 100 has a flat shape, and a coupling jaw 122 for coupling with the upper case 110 is formed along an edge thereof.

The lower case 120 is provided with a circuit unit 200 for computer signal processing of the operation of each button 112, 114, 115, the wire 210 connected to the circuit unit 200 is the lower case 120 It is pulled forward and connected to the computer.

On the circuit board 220 of the circuit unit 200, a switch unit 300 for transmitting the operation signal of the first and second buttons 114 and 115 and the wheel button 112 to the circuit unit 200 is installed. The switch unit 300 is divided into first, second and third switches 300a, 300b and 300c connected to the first and second buttons 114 and 115 and the wheel button 112, respectively.

In the middle portion of the circuit board 220, a blocking member 400 having elasticity and sound absorption, such as a sponge material having a suitable thickness and height, is placed across the circuit board.

In addition, a plurality of shock absorbing members 500, such as rubber or nonwoven fabric, are attached to a portion of the circuit board contacting the presser 116 of the upper case 110.

The upper case by reducing the vibration of the circuit board 220 due to the vibration generated during operation, and also the shock absorbing member 500 that the vibration is transmitted to the upper case 110 through the presser 116. The vibration of the vibration is greatly reduced, and the vibration noise generated from the circuit board 220 and the upper case 110 is reduced.

The blocking member 400 located in the middle portion of the circuit board 220 is pressed by the upper case and serves as a partition, so that the inner space of the mouse is naturally divided into both sides by the blocking member.

The sound is amplified louder as the ringing space becomes larger, but the ringing space on the side of the switch unit 300 becomes smaller due to the blocking member, so that the amplification of the noise generated in the switch unit is greatly reduced, and the sound absorbing blocking member 400 is part of the noise. The noise is further reduced while absorbing.

In addition, the blocking member 400 reduces the internal ringing space and absorbs noise, and also reduces the vibration of the upper case and the circuit board by pressing both sides between the upper case 110 and the circuit board 220. Noise is further reduced.

Various features of the present invention described above may be variously modified and combined by those skilled in the art, but such modifications and combinations reduce the transmission of vibrations to the upper case of the mouse or reduce the ringing space inside the mouse or operate it. If it is related to the configuration and purpose to absorb the noise should be considered to fall within the protection scope of the present invention.
